Question

an artificial satellite is moving in a circular orbit of radius 40000 km. calculate its speed if it takes 24 hours to revolve around the earth​

Answer 1

$\large\green{\textsf{✩ Verified Answer ✓ }}$

Given that :-

The radius of the orbit = 42250 km

Find out :-

Speed if it takes 24 hours to revolve around the earth

Solution :-

Therefore, circumference of the orbit = 2*π*42250km = 265571.42 km

Time taken for the orbit = 24 hours

Therefore, speed of the satellite = 11065.4 km.h-1

The satellite orbits the Earth at a speed of 11065.4 kilometers per hour.
